Preliminary .. PRELIMINARY White LED Driver with Automatic Dimming Control ! GENERAL DESCRIPTION The NJU6053 is a white LED driver with an automatic dimming control. It contains an output driver, a PWM controller, a luminance sensor control (power supply for sensor & A/D converter), a step-up DC/DC converter, a serial interface, etc. The NJU6053 can turn three independent lighting circuits on/off separately or simultaneously with instruction. The output driver ensures a 40mA maximum capability which allows the connection of 12 white LEDs (4 series x 3 parallels). Depending on the ambient light sensed with an external luminance sensor, the PWM controller controls...
